From 5d07bf264746b7c22d7104e0e2232eeea3d32296 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 8 Jul 2010 04:08:43 +0000 Subject: [PATCH] bnx2: 64 bit stats on all arches Now core network is able to handle 64 bit netdevice stats on 32 bit arches, we can provide them for bnx2, since hardware maintains some 64 bit counters.
